Another update on my own shit.
I did a test run with a friend of mine. All good. He had some ideas for improvements. And we also discussed different aspects of the app. Overall, it was a really nice experience. I would say it worked almost as expected. There's a stubborn bug related to the auth logic. Or maybe I'm just stupid. Anyway, I moved it to the backlog for now. I'll have to fix it anyway, but there are more important things to implement app wise.
Moving forward. Still a lot of work.
